The invention further comprehends the of illustration is shown the preferred em- Pf l P p y tapered p ntio th r l 1 provision of means for raising the wedge rectangular ing 2, in order to permit a new grip to be the same being formed with obtained upon the cable, and to this end there is provided a yoke member designated generally by the numeral 17.

This yoke is formed from a single strip of flat metal bent back upon itself to form a handle 18 and a fork at the inner end of the handle, th e furcationsl9 straddling the opposite (ifrtlue body 1 and be ingipivotally c'onnected thereto at points inwardly of the free end of said furcations as shown at20. The free end ortion ofeacly furcation is formed with a ongitudinallyextending slot 21, as clearly indicated in Figure 3 The body 1 is formed in its opposite sides with the longitudinally extending slots22 that have communication with the tapered opening 2 iand extend i ng th ough, the slotted ends, of Q'thfe furc ation s 13 f the; yok metaber and through e respective slots 2 fori ed ,inl'the sides. of the bod arefth e bo lts 23, the inner ends. thereof? being secured within suitable opeiiings proyi eglitherefor in the outer/sides oftl ije'gespec ive slips as indicatedin Figure 2., i

What we claim as new is:
